To all whom it may concern Be it known that 1, CHARLES WALTER LEE, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented new and usefulImprovements in Tool Holders, of which the following is a specification.

My present invention has reference to a tool holder. 1 7

My object is to produce a tool holder for machinists use, wherein steeltools, such as hits, of a comparatively short length, can be effectivelygripped.

A further object 'is to produce a tool holder'in which the stockisprovided with an angularly arranged socket, entering from one endthereof, the said socket having hingedly supported therein an elementdesigned to contact with the tool when the latter is arranged in thesocket, said hinged element being eng'aged'by screw which is threaded inthe stock for forcing the same against the tool when the latter isarranged in the socket, while means is provided for limiting theswinging of the said element in the direction of the tool.

The drawings illustrate an embodiment of the improvement.

In the drawings Figure l is a front elevation of a tool holderconstructedflin' accordance with this invention.

Figure 2 is an approximately central ver tical longitudinal sectionalview on the line 22 of Figure 1;

Referring now to the drawings iii-detail,

the numeral 1 designates the stock of my improved tool holder. The stockhas its headed end widened upon its upper face, as at 2, the end of thehead being arranged at an angle, and the lower corner of the said angleface being cut inwardly. The stock 1 is providedwith an angularlyarranged socket 23 that enters from the angle face thereof, the upperand end wall of the socket having a rounded transverse depression 4: forthe reception of the rounded eye 5 upon av plate or tongue 6. it pivot 7passes through the eye 5 and hingedly connects the plate or tongue (5 inthe socket. The socketis indicated, for distinc tion, by the numeral 8,andthe sidewalls, at the outer endthereof are provided "with lateraldepressions 9, the same being of a con-- siderable depth and receivingtherein lugs 10 formed upon the outer corners of the swinging plateortongue 6.

The head has a threaded opening which communicates with the socket, andengag ing the threads of the said'opening is the shank of a boltmemberll. The bolt memher contacts with the upper face of the plateshort length can be efl'ectively engaged'by.

the holder, and it is thought that the fQI6; going description, whentaken in connection with the drawings will fully set forth theconstruction, operation and advantages, of]

the improvement to those skilled" in the to which such inventionsrelate. 1 Having described the invention, 1 claim i 1. A tool includinga stock havingan anart gle socket entering from one end thereof, a I

plate arranged longitudinally in thesocke't' and havlng its innerendpivotally secured the-rein, means between the outer end of the plate andthe stock for limiting the swinging ofthe plate in the socket. and meansalso carriedbv the stock and adjustable thereon contacting the plateinward of said limiting means for swinging the same in the socket. 2. Atool holder including a stock having an angle socket'enterin g fromone'of its ends and extending through its base and be' ing provided witha transverse depression in a line with the wall of the socket at theterminal thereofa plate received in the,

socket having an eye portion disposed in,

the depression, a pivot passing through the eye securingthe plate -1nthe socket, said plate having its opposite end terminating in a linewith the outer end of the stock and its sides at its said end havinglaterally extending lugs, the side wallsprovided by the socket havinglateral depressions of a greaterdepth than the thickness of the lugsreceiving the lugs therein and limiting the.

swinging movement of the plate in the socket. and adjustable meanscontacting the a plate for swinging the same inwardly of the socket. r c

Intestimony whereof I affix my signature.
